In 1974, Hawking discovered black hole evaporation caused by thermal
radiation emitted by the black hole [1]}. Soon after, Unruh
in 1976 proposed a very important prediction based on the effect of
Hawking radiation, which says that a vacuum state observed by an
observer who stays in flat Minkowski spacetime would be detected as
a thermal state from another observer who hovers near the event
horizon of the black hole with uniform acceleration [2]}, [3]}.
In recent years, as the intersection of classical informatics,
quantum mechanics, special and general relativity and quantum field
theory, the problem of quantum information in non-inertial system
and curved spacetime has become a new hotspot in the research of
quantum information science [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]}, [14]}, [15]}, [16]}, [17]}, [18]}, [19]}, [20]}, [21]}, [22]}, [23]}, [24]}, [25]}, [26]}, [27]}, [28]}, [29]}, [30]}.
Undoubtedly, the study of quantum information under the framework of
relativity, especially in the non-inertial frame and curved
spacetime, not only is of great significance to the
development and perfectness of quantum information theory, but also
plays a positive role in understanding the entropy and information
paradox in black holes. For examples, Fuentes et
al. [4]} show that the entanglement in noninertial frames
is characterized by the observer-dependent property.
Martín-Martínez et al. [7]} studied the entanglement
degradation affected by the Hawking effect of Schwarzschild black
hole. Mann et al. [15]} pointed out that incorporating concepts
from quantum theory into relativity can yield novel and interesting
effects. More recently, Wu et al. [28]} studied the GTN and
the genuine tripartite
entanglement (GTE) of Dirac fields in the background of a Schwarzschild black
hole. Li et al. [29]} explored the tripartite entropic
uncertainty and genuine tripartite quantum coherence of Dirac fields
in the background of the Garfinkle-Horowitz-Strominger (GHS)
dilation space-time.
